warns-omens ATTACHMENT.

Application filed January 5, 1922. Serial no. 527,211.

To all whomz't may concern-1 Be it known that we, JAiuns W. RAMSDELL andFREDERICK if. l i insr. citizens of the Unitec States, residing atLalreland, county of Polk, State of Florida, and Tampa, in the county ofllillsborough and State of Florida, respectively, have invented certainnew and useful Improvements in "Water- Closet Attachments, of wh ch thefollowing is a specification. i

This invention relates to water closets,

and has for its object to provide an 1111- proved device adapted toprevent the flow of water to the closet if and when the closet bowlbecomes full and in danger of overflowing.

Closet bowls and the waste pipes therefrom frequently become clogged,and this clogging is often followed by one or more operations of theflush tank. resulting in overflowing and disagreeable renditions. Bymeans of the present invention l provide an automatic valve which isoperated by a float located in the bowl, and when the water rises to acertain heighth in the bowl, the valve or valves close and automatically shut off the further flow of water from the flush tank.

The invention may be embodied in various forms, one of which isillustrated in the accompanying drawings, in which Fig. 1 is a partialhorizontal section of the upper part of a bowl provided with theimprovement. Fig. 2 is a section on the line 2-2 of Fig. 1.

In the drawings, the body of the bowl is indicated at 10, the rim at 11and the inlet chamber to the rim at 12. This inlet chamber communicateswith the hollow 13 of the rim, so that water may flow around the rim ofthe bowl and is discharged into the bowl through holes 9 in the underpart of the rim. This rim overhangs the side of the bowl inwardly.

At or in front of the inlet chamber 12 the rim of the bowl is providedwith a wall 14; which defines a part of the water passage 13, and ateach end of this wall 1 1 1 form a circular valve opening 15 whichpermits flow from the inlet chamber 12 to the hollow rim. Each of theseopenings is controlled by a ball valve 6 which may also seat at 16 atthe upper end of an opening 8 extending through the lower wall of therim and provided with a valve seat 18 at its lower end. Each ball 6 isflexibly or loosely connected toa valve member 7 q carried by a circularfloat 20 having the form of a ring which fits in the space under the rimof the bowl and is adapted to be lifted when thewater in the bowlreaches the heighth thereof; The connec tion between each ball valve 6and the float may be of various forms. l have shown a short rod 21 whichhasa ball and socket joint 22 with the apex 'ofthe valve member T, andaloose or ball and socket joint 23 with the ball 6. Instead of thisjointed rod, a flexible connection such as a spiral spring may besubstituted, and the ball is preferably made heavy enough to tend toseat by itsownweight ontheseat 16, and, when the floatis lifted, theballs are lifted from the seats 16 and in consequence of the waterpressure and direction of flow they will swing over and seat at theopenings 1:") between the supply chamber and the hollow mm.

In operation, the float will normally remain in lowered position, withthe valves 6 resting against the seats 16. This permits the water toflow from the supply chamber through the ports 15 to the hollow rim, andthe closet operates as usual. When. the closet becomes clogged the riseof the water will lift the float 20 and thereby raise the valves 6permitting them to be forced by the water pressure against the seats 15,thereby sealing the passages to the hollow rim and cutting off the watersupply. And at the same time, the valve members 7 will rise with thefloat and close against the seats 18, thereby closing the holes throughwhich the connections 21 work and preventing the escape of any waterthrough said. holes. When the float falls the reverse action occurs andthe parts are restored automatically to original position.

The structure therefore provides automatically actuated means forcutting 0fi the water supply to prevent overflowing, and no manualoperation is necessary either to prevent said flow or to restore normalconditions when the clogging is relieved.

The invention may be embodied in various forms and no limitation in thisrespect is implied.

We claim:

1. The combination with a closet bowl having a supply chamber at the rimthereof, and. an outlet from said supply chamber to the rim, and anopening in the lower wall of said supply chamber, of a float in thebowl, and a valve located in the supply chamber and flexibly connectedto the float and controlling said outlet and said opening respectively,said valve being adapted to close said outlet when the float is liftedand to close said opening when the float is lowered.

2. The combination with a closet bowl having a supply chamber at the rimthereof and a hOllOW rim having outlets into the bowl and also having anopening conmeeting the supply chamber and the rim and another openinginto the bowl, of a float in the bowl, a valve in the supply chamber,movable from one opening to the other to close either, and a flexibleconnection between the float and the valve, said connection extendingthrough the last mentioned opening. a

The combination with a closet bowl having an overhanging rim and supplychamber, an opening from the supply chamber to the rim, and anotheropening in the lower wall of the supply chamber, of a float located inthe bowl, a ball valve movable in the supply chamber to close either ofsaid openings, a flexible connection between th float and the ballvalve, said connection extending through the opening in'the lower wallof the supply chamber, and a valve member carried by the float andadapted to close upwardly against said opening in the lower wall or" thesupply chamber when the float lifts.
